Abstract
A kind of general gasoline engines without catalyst discharge structure, be provided with without catalyst discharge structure body, combustion system and oil supply system is provided with without catalyst discharge structure body, combustion system is provided with fan guard, combustion system is other is provided with crank-connecting rod piston, piston adopts the narrow groove structure of flat-top, piston adopts the narrow groove structure of flat-top, reduce the fricative heat of countercylinder wall when piston runs, burning becomes more complete, discharge can not be affected, charging efficiency and velocity of combustion can be improved, reduce remaining inflammable gas to discharge, an aeration valve installed by fan guard, when high blast, can to baffler oxygenating, under the high-temperature gas of exhaust, help secondary so to burn, discharge after inflammable gas as much as possible in baffler burnouts in secondary so burns, cylinder head combustion-chamber shape is oblique shape basin type, inflammable gas can be improved and enter the inflation after cylinder and scavenging speed.
Description
Technical field
The utility model relates to a kind of tapping equipment, be specifically related to a kind of general gasoline engines without catalyst discharge structure.
Background technique
The discharge of general gasoline engines is a technical barrier in logical machine field, in order to logical machine discharge meets U.S. EPA, Europe 3 standard in Europe, general use noble metal catalyst is carried out secondary combustion and is reached effluent standard, improve manufacture cost and reduce enterprise competitiveness, use and can reduce costs without catalyst discharge structure, improve the technological element of a product, improve market competitiveness of enterprises, because the component of existing general gasoline engines are produced, domestic technique falls behind, the discharge value of the finished product machine of producing is 1-1.5 times of US and European limit value, in order to ensure the standard limit reaching legal provisions to exported country, noble metal catalyst must be installed, cost of production increases, competitive ability declines, add that the deteriorated cycle of metal solvent is short, at all after dates of deterioration, discharge can be doubled and redoubled, befouling environment, business risk is larger.
Summary of the invention
It is high that the purpose of this utility model is to provide a kind of charging efficiency, a kind of general gasoline engines of emission standard without catalyst discharge structure.
The technical solution of the utility model is: a kind of general gasoline engines without catalyst discharge structure, be provided with without catalyst discharge structure body, described is provided with combustion system and oil supply system without catalyst discharge structure body, described combustion system is provided with fan guard, described combustion system is other is provided with piston, described piston adopts the narrow groove structure of flat-top, the annular groove width of described piston is 1mm, oil groove width is 2.5mm, described piston is other is provided with piston ring, the width of described piston ring is 1mm, and oil ring is 2.5mm.
Described fan guard is provided with aeration valve and air gathering plate, and described aeration valve carries out supplemental oxygen to baffler under the effect of high blast.
Described is provided with cylinder head without catalyst discharge structure body, is provided with firing chamber in described cylinder head, and the shape of described firing chamber is oblique shape basin type structure.
The utility model has the advantages that: piston adopts the narrow groove structure of flat-top, reduce the fricative heat of countercylinder wall when piston runs, burning becomes more complete, discharge can not be affected, charging efficiency and velocity of combustion can be improved, reduce remaining inflammable gas to discharge, an aeration valve installed by fan guard, when high blast, can to baffler oxygenating, under the high-temperature gas of exhaust, help secondary so to burn, discharge after inflammable gas as much as possible in baffler burnouts in secondary so burns, cylinder head combustion-chamber shape is oblique shape basin type, inflammable gas can be improved and enter the inflation after cylinder and scavenging speed, inflammable gas mixing is more abundant, reduce and so burn angle to death, improve heat energy efficiency and the effective working pressure in firing chamber.Keep the stability that kinetic energy exports.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is firing chamber, 2 is piston, and 3 is fan guard.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
A kind of general gasoline engines without catalyst discharge structure, be provided with without catalyst discharge structure body, combustion system and oil supply system is provided with without catalyst discharge structure body, combustion system is provided with fan guard 3, combustion system is other is provided with piston, piston 2 adopts the narrow groove structure of flat-top, the annular groove width of piston 2 is 1mm, oil groove width is 2.5mm, piston 2 is other is provided with piston ring, the width of piston ring is 1mm, oil ring is 2.5mm, fan guard 3 is provided with aeration valve and air gathering plate, aeration valve carries out supplemental oxygen to baffler under the effect of high blast, cylinder head is provided with without catalyst discharge body, firing chamber 1 is provided with in cylinder head, the shape of firing chamber 1 is oblique shape basin type structure.
